<h1>What is FRCM?</h1>



<div class="row">
  <div class="col-sm-12 col-md-8">
    
    <p>
      Repair, protect and strengthen aging, damaged or overloaded concrete and
      masonry structures in one application and significantly reduce your
      installed cost.
    </p>

    <p>
      FRCM or Fabric-Reinforced Cementitious Matrix combines high-performance
      sprayable mortar with a carbon-fiber grid to create thin-walled,
      reinforced concrete shells without adding significant weight or mass to
      the structure.
    </p>

    <h2 class="h4">Benefits</h2>

    <ul>
      <li>
        Repair and strengthen structures using only a thin layer of material
      </li>
      <li>
        Can be applied in multiple grid layers (four maximum) to achieve desired strengthening – 1/2"-1" (12.7-25.4 mm) thick for one-layer grid applications, adding 1/2" (12.7 mm) for each additional grid layer
      </li>
      <li>
        Lightweight system for vertical surfaces and overhead applications
      </li>
      <li>
        Suitable for harsh environments or service conditions including marine
        locations, elevated temperatures, humidity, abrasion and UV
      </li>
      <li>Works on damp substrates</li>
      <li>
        Installation process is similar to that for wet shotcrete repair mortars
      </li>
      <li>
        Quick installation with less preparation than traditional shotcrete
        repairs with rebar
      </li>
      <li>Does not create a vapor barrier</li>
      <li>Matches substrate finish</li>
      <li>100% solids formulation</li>
      <li>
        Carbon-fiber grid features excellent chemical and corrosion resistance
      </li>
      <li>Non-hazardous shipping</li>
    </ul>
